OBJECTIVE To determine whether gender differences exist in lower extremity joint motions and energy absorption landing strategies between age and skill matched recreational athletes. DESIGN Mixed factor, repeated measures design. BACKGROUND Compared to males, females execute high demand activities in a more erect posture potentially predisposing the(More)
PURPOSE The aim of this study was to calculate and explain the pattern of force transmitted to the anterior cruciate ligament during soft-style drop-landings. We hypothesized that peak ACL loading is due to the anterior pull of the quadriceps on the tibia, as these muscles develop large eccentric forces upon impact. METHODS A three-dimensional model of(More)
Persons with spinal cord injury (SCI) are at a heightened risk of developing type II diabetes and cardiovascular disease. The purpose of this investigation was to conduct an analysis of metabolic, body composition, and neurological factors before and after 10 weeks of functional electrical stimulation (FES) cycling in persons with SCI. Eighteen individuals(More)
OBJECTIVES (1) To identify adaptations caused by intra-articular knee joint effusion during walking and (2) to determine if knee joint effusion may be a causative factor in promoting quadriceps avoidance gait patterns. DESIGN Gait testing of 14 healthy individuals who underwent incremental saline injections of the knee joint capsule.Background. Gait(More)
PURPOSE The purpose of this study was to determine whether fully rehabilitated ACL reconstructed (ACLr) recreational athletes utilize adapted lower-extremity joint kinematics and kinetics during a high-demand functional task. METHODS The kinematic and kinetic performance of 11 healthy and 11 hamstring ACLr recreational athletes were compared during a(More)
PURPOSE The purpose of this study was to determine whether walking with poles reduces loading to the lower extremity during level over ground walking. METHODS Three-dimensional gait analysis was conducted on 13 healthy adults who completed 10 walking trials using three different poling conditions (selected poles, poles back, and poles front) and without(More)
BACKGROUND It is common for hip arthroscopy patients to demonstrate significant gluteus medius muscle weakness and concurrent iliopsoas tendinitis. Restoration of gluteus medius muscle function is essential for normal hip function. HYPOTHESIS A progression of hip rehabilitation exercises to strengthen the gluteus medius muscle could be identified that(More)
The purpose of this study was to determine the validity of the belly-press test as a clinical test for the subscapularis muscle with the use of electromyography (EMG). In addition, the belly-press and lift-off tests were compared to determine whether the two physical examination techniques are equivalent in their evaluation of the upper and lower portions(More)
INTRODUCTION The quadriceps avoidance gait pattern may not be as common in ACL deficient (ACLd) gait as previously described. PURPOSE The purpose of this study was to investigate the existence of the quadriceps avoidance pattern in ACL deficient patients and to further identify gait compensations that may exist in this subject pool. METHODS In the(More)
PURPOSE The purpose of this study was to compare the forearm supination and elbow flexion strength of the upper extremity in patients who have had an arthroscopic long head of the biceps tendon (LHBT) release with patients who have had an LHBT tenodesis. METHODS Cybex isokinetic strength testing (Cybex Division of Lumex, Ronkonkoma, NY) was performed on(More)
